PORT TOWNSEND — Cars and trucks will smash into each other, filling the air with roars and the sound of smashing metal, during three demolition derbies at the 14th annual Jeffco Expo on Saturday and Sunday.

In separate events, adults and youths too young to have driver's licenses will bash and crash cars and trucks during the demolition derbies on the last day of the expo at the Jefferson County Fairgrounds, 4907 Landes St.

“You hit each other until you're the last car moving and you win,” said Ed Neet, the owner of Peninsula Recycling and Auto Wrecking of Port Townsend who organized the car and truck events.

“You'd be surprised how smashed up a car can get and still move,” he added.

Gates will open at the Jeffco Expo at 9 a.m. both days and close at 5 p.m.

Admission will be $5 for those 12 and older Saturday and $8 Sunday. Those 11 and younger and active military with current identification will be admitted free each day.

The event usually draws about 2,000 people, said Sue McIntire, fair office manager and Jefferson County Fair Association board treasurer.

“We hope for more this year,” she said.

The fair and fairgrounds are maintained year-round by the fair association, she said.

“We support ourselves through campground and building rentals, RV and boat storage, and events such as this,” Mc-Intire said.

The car and driver fee is $50, Neet said. Crew pit passes are $20. Registration to participate in the grandstand events will begin at 8 a.m. each day.

Tough truck contest

Before the heats for the demolition derbies begin Sunday, a tough truck competition will rev up in the grandstand at 11 a.m.

On Saturday, also starting at 11 a.m. in the grandstand, fairgoers can watch trucks, cars and quads in dirt drags and on an obstacle course.

And both Saturday and Sunday, they can, for $5 each, get a ride in a monster car — a 1965 Thunderbird atop a 1953 military frame with huge tires — as it rolls over an obstacle course that includes a car, big tires, logs and a hole, Neet said.

He expects at least 10 cars in the kids' derby and at least a dozen in the adult derbies.

The other vehicle events have drawn about 20 vehicles in the past, he said.

The grandstand events will begin in the afternoon after the heat races, which begin at 11 a.m., are finished.

Neet said the times for the main events each day will depend on how many cars compete in the preceding heats.

Kids' Derby

Sunday's demolition derbies will begin with the Kids' Derby, in which those between 10 and 15 years old compete in small cars.

“If you have a driver's license, you can't be in the Kids' Derby,” Neet said.

The first Kids' Derby was in 2012, Neet said.

This year's adult demolition derby — with adults competing in small cars first and then in large cars and trucks — will be the third held since 1979.

Neet himself plans to compete. He will drive a 1970 Ford Ranchero.

His son, Chad, 17, also will join the demolition contest, driving a 1966 Plymouth.

“Friends from Port Angeles, Forks and Kitsap County are coming, too, and bringing their cars,” Neet said.
